<!--
   This testcase checks that we don't clamp negative opacity values to their
   valid range [0,1] until *after* we've done animation & interpolation.
   If we clamped intermediate results too early (e.g. after parsing, during
   interpolation, or right after we add the first animation's interpolated
   value), we'd end up with the wrong intermediate opacity values here.
